Abstract Organophosphorus chemistry was developed in the last decade by promoting the synthesis reactions using ionic liquids either as solvent or catalyst. Ionic liquids (ILs), the so-called “green solvents”, have gained interest in the synthesis of organophosphorus compounds as alternatives to flammable and toxic organic solvents and catalysts. ILs have beneficial properties because they provide high solubility for many organic and inorganic compounds or metal complexes, have no vapor pressure, and are reusable. Also, in some cases, they can enhance the reactivity of chemical reagents. In this review, we aimed at showing the synthesis of different organophosphorus compounds under green and mild conditions using ILs as reaction media or catalysts, according to a trend developed in the last years. A novel trend is to perform these syntheses under microwave irradiation conditions together with ILs as solvents and catalysts.

Imidazolium Ring

The multixenobiotic/multidrug resistance (MXR/MDR) system controls transport of foreign molecules across the plasma membrane as a preventive measure before toxicity becomes apparent. The system consists of an efflux pump, ABCB1, and/or a member of the ABCC family. Ionic liquids are broadly used solvents with several unique properties such as wide liquid range, negligible vapor pressure, good thermal and chemical stability and extraordinary dissolution properties for organic and inorganic compounds. Ionic liquids containing imidazolium ring are frequently used as solvents in drug synthesis. Constitutive and induced amounts of ABCB1 and ABCC1 proteins were estimated here by Western blotting and quantified by flow cytometry in HeLa cells exposed to three homologous 1-alkyl-3-methylimidazolium and one benzyl ring substituted salts. Aliphatic substituents in position 1 of the salts caused a weak toxicity but 1-benzyl ring was strongly toxic. An 8-day long treatment with 10(-4) M 1-hexyl-3-methylimidazolium chloride resulted in an about 1.5-fold increase of ABCB1 level and over 2-fold increase of ABCC1 level. The amounts of both investigated ABC-proteins were linearly dependent on the length of the imidazolium ring side chain. Such distinctive changes of the amount of MXR/MDR proteins measured in cultured cells may be a useful marker when screening for potential toxicity of various chemicals.

The high-temperature syntheses of the low-valent halogenides P2I4, Te2Br, a-Te4I4, Te4(Al2Cl7)2, Te4(Bi6Cl20), Te8(Bi4Cl14), Bi8(AlCl4)2, Bi6Cl7, and Bi6Br7, as well as of WSCl4 and WOCl4 have been replaced by resource-efficient low-temperature syntheses in room temperature ionic liquids (RTILs). The simple one-pot syntheses generally do not require elaborate equipment such as two zone furnaces or evacuated silica ampoules. Compared to the published conventional approaches, reduction of reaction time (up to 80%) and temperature (up to 500 K) and, simultaneously, an increase in yield were achieved. In the majority of cases, the solid products were phase-pure. X-Ray diffraction on single crystals (redetermination of 11 crystal structures) has demonstrated that the quality of the crystals from RTILs is comparable to that of products obtained by chemical transport reactions.
